    • Cardiovascular and thermal strain during 3–4 days of a metabolically demanding cold‑weather military operation 

      Castellani, John W.; Spitz, Marissa G; Karis, Anthony J.; Martini, Svein; Young, Andrew J; Margolis, Lee M; Karl, J Philip; Murphy, Nancy E; Xu, Xiaojiang; Montain, Scott J; Bohn, Jamie A; Teien, Hilde Kristin; Stenberg, Pål H.; Gundersen, Yngvar; Pasiakos, Stefan M (2017)
      Background Cardiovascular (CV) and thermal responses to metabolically demanding multi-day military operations in extreme cold-weather environments are not well described. Characterization of these operations will provide ...

    • Changes in intestinal microbiota composition and metabolism coincide with increased intestinal permeability in young adults under prolonged physiologic stress 

      Karl, J Philip; Margolis, Lee M; Madslien, Elisabeth Henie; Murphy, Nancy E; Castellani, John W.; Gundersen, Yngvar; Hoke, Allison V; Levangie, Michael W; Kumar, Raina; Chakraborty, Nabarun; Gautam, Aarti; Hammamieh, Rasha; Martini, Svein; Montain, Scott J; Pasiakos, Stefan M (2017)
      The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military ...

    • Effects of a 7-days military training exercise on inflammatory biomarkers, serum hepcidin, and iron status 

      McClung, James P; Martini, Svein; Murphy, Nancy E; Montain, Scott J; Margolis, Lee M; Thrane, Ingjerd; Spitz, Marissa G; Blatny, Janet Martha; Young, Andrew J; Gundersen, Yngvar; Pasiakos, Stefan M (2013)
      Background Hepcidin, a peptide that is released into the blood in response to inflammation, prevents cellular iron export and results in declines in iron status. Elevated serum and urinary levels of hepcidin have been ...

    • Effects of exercise mode, energy, and macronutrientinterventions on inflammation during military training 

      Pasiakos, Stefan M; Margolis, Lee M; Murphy, Nancy E; McClung, Holy L; Martini, Svein; Gundersen, Yngvar; Castellani, John W.; Karl, James P.; Teien, Hilde Kristin; Madslien, Elisabeth Henie; Stenberg, Pål H.; Young, Andrew J.; Montain, Scott J; McClung, James P (2016)
      Load carriage (LC) exercise may exacerbate inflammation during training. Nutritional supplementation may mitigate this response by sparing endogenous carbohydrate stores, enhancing glycogen repletion, and attenuating ...

    • Effects of Supplemental Energy on Protein Balance during 4-d Arctic Military Training 

      Margolis, Lee M; Murphy, Nancy E; Martini, Svein; Gundersen, Yngvar; Castellani, John W.; Karl, James P.; Carrigan, Christopher T; Teien, Hilde Kristin; Madslien, Elisabeth Henie; Montain, Scott J; Pasiakos, Stefan M (2016)
      Soldiers often experience negative energy balance during military operations that diminish whole-body protein retention, even when dietary protein is consumed within recommended levels (1.5-2.0 g[middle dot]kg-1[middle ...
